PRINCESS ANNE, Md. (WJZ) — The hunt to find the person who murdered a University of Maryland Eastern Shore student continues. And state police have a new tool to help them catch the killer.

Derek Valcourt explains detectives are releasing some new security camera footage taken near the crime scene.

The video doesn’t show the murder itself. But it does show people walking and driving by–people police need to find.

The murder happened just out of camera range of the surveillance video. It was snowing around 9 p.m. Saturday. You can see a group of at least three people walking by, car after car drives by as well. Someone walks by carrying an umbrella. State police are asking what–if anything–did these people see?

“These are potential witnesses that we need to speak to,” said Det. Sgt. Scott Cook, Maryland State Police.
